(continued ...) it off while at the same time trying to blow out any chunks. Rinse from the inside out (opposite to normal air flow). Clean out any remaining debris in the bottom of the unit.
While you have everything apart examine the condenser fan motor. Some motor models have lubrication ports that may have a plastic plug. This would be an excellent time to put a few drops of oil into the lubrication ports. This will lower friction and increase the motor efficiency. Check for oil ports on the spindle shaft end bearings. Remove the plugs, put in a few drops of general purpose heavier oil and replace the plugs. Don't use thin light weight oil. If there are no ports, then don't arbitrarily squirt oil on anything. Likely in the no-oil-port styles, these are sealed maintenance free bearings in the motor.
Extra credit DIY (difficult): If you are this far into the unit, you might as well examine the motor name plate and manufacturer's stickers. Does it say 'Premium High Efficiency', 'Standard Efficiency' or anything about efficiency anywhere? If it states High Efficiency Premium, then you are done. If it says Standard or does not state anything about High Efficiency, then there is a remote opportunity to increase your system efficiency. Identify the motor mounting style. Do an Internet search for the manufacturer and model number. There is a sizable list of possible mountings and sizing. With a bit of work, you can locate a high efficiency premium motor replacement. The energy savings for a high efficiency motor upgrade will likely pay for itself in 2 to 4 years depending on your cooling season length.
